Garbage classification code generation method

Abstract

The invention discloses a garbage classification code generation method. The method comprises the following steps: encoding garbage bag identity information to generate a unique garbage bag identity code; extracting an identity display code and an identity hidden code, and converting the identity display code into numerical data; carrying out calculation to obtain an initial value, parameters, aninitial iteration step number and an iteration interval step number of a chaotic system, and carrying out iteration to generate a chaotic sequence; scrambling the identity hidden codes in the garbageidentity codes by utilizing a position change rule before and after chaotic signal sorting; performing conversion between characters and numerical values; obtaining a corresponding numeric sequence; performing corresponding forward diffusion encryption and reverse diffusion encryption according to different numerical values in the numeric sequence to complete conversion of the numerical values andcharacters, thereby generating an identity hidden encryption code, and further combining and generating the garbage classification code, and obtaining the garbage classification two-dimensional codewith the garbage classification mark at the same time. The garbage classification code generation method provided by the invention is simple and feasible, has very high safety and is not easy to crack, the generated garbage classification code is convenient for guiding garbage classification, the privacy of a user in garbage bag identity hidden information can be effectively protected, and the garbage classification code has uniqueness and safety.

Description

technical field [0001] The invention relates to the field of garbage classification, in particular to a method for generating garbage classification codes. Background technique [0002] In recent years, with the rapid development of the global economy and the rapid increase in population, the scale of cities has continued to expand, resulting in a sharp increase in the amount of municipal solid waste, and the problem of municipal solid waste is deteriorating into a global crisis. The land erosion and environmental pollution caused by the "garbage siege" not only seriously threaten the public's health, but also become one of the factors that affect and restrict the sustainable development of cities in my country and even in the world. To solve the dilemma of "garbage siege", the most important thing is to realize the reduction of urban domestic waste from the source, and complete the recycling and harmless treatment of waste. Therefore, promoting the classification of domesti...

Problems solved by technology

[0003] The implementation of urban garbage classification in my country is relatively slow. The main reason is that the garbage classification codes on garbage bags either lack confidentiality or are difficult to understand the classification. For citizens who lack garbage classification knowledge, it is not clear which category a lot of garbage should belong to. If you don’t know, this will lead to conscious and unconscious littering, making the classification useless; at the same time, you still have doubts about whether the identity information of the garbage bag will leak the user’s privacy, and the worry that personal information will be exposed has also hit people to a certain extent.
